Development of a promising technology for the embedded elements manufacture to obtain guide vanes for the turbopump units

The paper identifies technological problems in manufacture of a guide vane for the liquid propellant rocket engine turbopump unit. It considers types of the guide vanes and their design features and describes the most widely used methods of the guide vanes manufacture in mechanical engineering. Their advantages and disadvantages are noted. A method of manufacturing the turbopump unit guide vanes by hot isostatic pressing of small granules using the embedded element is analyzed. The paper proposes a promising technology in the aerospace products manufacture using the electrical discharge machining. It ensures high accuracy of the linear dimensions of the embedded elements curved surfaces and makes it possible to produce profile disks with small inter-blade channels and thin edges.
